Light source device, light source control method, and image acquisition system

A light source control method comprising:

• emitting a plurality of types of lights;
• and
• causing the plurality of types of lights to be incident on an optical waveguide unit, the optical waveguide unit multiplexing the plurality of types of lights and then guiding multiplexed light to an image acquisition device that acquires an image of as imaging object, wherein
• when the plurality of types of lights is caused to be incident on the optical waveguide unit, on an incident surface of an incident unit on which the plurality of types of lights is incident, with a predetermined position of the incident surface as a reference position, maximum separation distances are caused to be equal to each other from the reference position to incident positions of the respective plurality of types of lights.

An image acquisition system comprising:

• an image acquisition device including an imaging unit that images an imaging object;
• and
• a light source device that emits illumination light used when the imaging unit images the imaging object, wherein
• the light source device includes:
• a light source unit that emits a plurality of types of lights;
• an optical waveguide unit that multiplexes the plurality of types of lights and then guides multiplexed light to the image acquisition device;
• and
• an incident unit that causes the plurality of types of lights to be incident on the optical waveguide unit, wherein.
• on an incident surface of the plurality of types of lights in the incident unit, with a predetermined position of the incident unit as a reference position, maximum separation distances are equal to each other from the reference position to incident positions of the respective plurality of types of lights incident on the incident unit.
